Hey @thedanotto, sorry for the confusion. The symbolic link needs to be created to point at your existing vimrc file, whereever that is on your computer. The second argument, .vimrc will always be the same as Vim always looks to the same file, specifically ~/.vimrc for configuration.
As an example:
$ pwd
/Users/christoomey/other-code/vim
$ ls
vimrc
$ cd ~
$ pwd
/Users/christoomey
$ ln -s ~/other-code/vim/vimrc .vimrc
After making the symlink you can confirm it is set by running
$ ls -laFG .vimrc
lrwxr-xr-x 1 christoomey staff 42 Jul 1 11:58 .vimrc@ -> /Users/christoomey/code/dotfiles/vim/vimrc
It should point to the actual file. You can also cat the file from your home dir to confirm.
I’ve also updated the video notes to match the video. Thanks for the heads up on that!
